Did evening primrose make you sick?

Yesterday I started taking epo, I took 2 1000mg and I was fine until this morning when I woke up I run to the bathroom because I was going to be sick..I wasn't actually sick but I felt it coming up then after about a minute it went away..has this happened to anyone else? I'm asking because am not sure if it was the epo or might have been something I ate.
